class one

Question 1

what is rate produced pressure

Answer 1

HR x SBP

Question 2

what is cardiac output

Answer 2

HR x stroke volume

Question 3

what happen to our BP when we exercise

Answer 3

SBP elevated

DBP remain level

Question 4

what is the best estimate of the increased metabolic demand on the heart

Answer 4

rate produced pressure

this is a repersentation of the myocardial O2 demands

Question 5

what are the stages of HTN

Answer 5

Normal: Blood pressure is less than 120/80 mm Hg

Elevated: Blood pressure is 120–129/less than 80 mm Hg

Stage 1 hypertension: Blood pressure is 130–139/80–89 mm Hg

Stage 2 hypertension: Blood pressure is 140/90 mm Hg or higher

HTN crisis - 180/120

Question 6

what is the electrical path of the heart

Answer 6

SA
AV
bundle of his
purkinjie fibers

Question 7

what is VO2 max

Answer 7

a measurement of how much oxygen a person can use during intense exercise

the amount of oxy that you can consume

Question 8

why do we train at a higher altitude

Answer 8

there is less oxy at higher altitude

the body get used to creating more red blood cells and this is benificial when you come back to sea level

Question 9

with increase in altitude what happesn to HR, SV, CO, BP

Answer 9

increase in: HR, CO, BP

stable: SV

this is a result of less o2 being available

Question 10

what is acclimization

Answer 10

this is when we stay at a higher altitude

Question 11

what happens to HR, SV, CO, BP with acclimization

Answer 11

increase: HR

normal: BP an CO

decrease: SV

Question 12

under water what happens to our vital signs

Answer 12

BP - decreases

HR - decreases

CO - increases

SV - increase

venous return - increases
- increase in SV

Question 13

what is vital capacity

Answer 13

how much air we can breath in

Question 14

what do beta blockers do

Answer 14

decrease HR

complete with nor and epi for the beta agrengenric receptors of the heart

Question 15

beta blockers are presribe to what hind of pts

Answer 15

htn and cornary artery disease

Question 16

what do beta blockers end with

Answer 16

lol

Question 17

what is Aortic Auscultation Landmarks

Answer 17

2nd IC space, right sternal border

Question 18

what is Pulmonic Auscultation Landmarks

Answer 18

2nd IC space, left sternal border

Question 19

what is tricuspid Auscultation Landmarks

Answer 19

4th IC space, left sternal border

Question 20

what is Mitral Auscultation Landmarks

Answer 20

5th IC space, midclavicular line

Question 21

HR compared in fit and unfit people

Answer 21

unfit people it takes longer for the heart rate to return to resting rate

Question 22

what is s1 sound

Answer 22

“lub”; closure of mitral and tricuspid valves, onset of systole

Question 23

what is s2 sound

Answer 23

“dub”; closure of aortic and pulmonary valves, onset of diastole

Question 24

what is s3 heart sound

Answer 24

“ventricular gallop”; ventricular filling, associated with heart failure

Question 25

what is a s4 heart sound

Answer 25

“atrial gallop”; abnormal, ventricular filling and atrial contraction HTN, ventricle hypertrophy

Question 26

where is the s2 sound the loudess

Answer 26

the base of the heart (the top)

Question 27

where is s1 sound the loudest

Answer 27

apex of the heart

Question 28

what is SV

Answer 28

amount of blood pumped per HR

Question 29

HR and CO in response to increasing work rate

Answer 29

HR and CO increase linearly with work rate reaches plateua at 100% VO2 max

Question 30

what does the diastolic BP represent

Answer 30

with the heart is not pumping when the heart is relaxed

Question 31

BMI of what means obesity

Answer 31

30

Question 32

do we use the term per-hypertension anymore

Answer 32

no

Question 33

sym vs para sym

Answer 33

sym - fight or flight para- rest and digest

Question 34

weight bearing in water

Answer 34

weight bearing drops as the water deepens

Question 35

what is the RPE scale between

Answer 35

6-20

Question 36

20 on the borg RPE scale

Answer 36

max exertion

Question 37

15 on the RPE scale

Answer 37

very hard

Question 38

11 on RPE scale

Answer 38

light

Question 39

how can the sym NS be influence SV

Answer 39

increases contraction strength - this influences SV

Question 40

what is pre load

Answer 40

left ventricular end diastolic volume the amount of ventricular stretch after diastole

Question 41

what is after load

Answer 41

systematic vascular resistance the amount of resistance the heart must overcome to open the aortic valve and push the blood volume into systemic circulation the amount of resiatnce you need to open the aortic valave

Question 42

pre load and after load effect on stroke volume

Answer 42

per load - increase SV after load - decrease SV

Question 43

what is frank starling law

Answer 43

the stroke volume of the left ventricle will increase as the left ventricular volume increases due to the myocyte stretch causing a more forceful systolic contraction.

Question 44

what is the wong baker scale

Answer 44

faces to help a person effectively communicate the severity of their physical pain.
